Knauf Drywall Plasterboard - Square Edge - 2400 x 1200 x 9.5mm

The main advantages are its dimensional stability, resistance to rot and warping, and enhanced acoustic performance compared to standard plasterboard.

While the ivory paper face is suitable for direct decoration, applying a primer first is recommended for a more uniform and professional paint finish.

For optimal results, use Knauf jointing compounds and tape over the seams after fixing the boards. Ensure joints are clean and dry before applying compound.

You can easily cut the board using a sharp utility knife and a straight edge to score the surface, then snapping the board along the score line.

While resistant to rot and warping, it is not a moisture-resistant board. For areas with high humidity like bathrooms or kitchens, consider specialized moisture-resistant plasterboard.

Each sheet measures 2400 x 1200mm and covers 2.88 square meters.

This particular board is 9.5mm thick.

Ensure you are using a sharp utility knife and applying consistent pressure when scoring. A single, decisive score is usually more effective than multiple shallow ones.

Ensure joints are properly taped and filled with sufficient coats of jointing compound. Allow adequate drying time between coats and avoid applying compound too thickly in one go. Ensure the underlying framework is stable and not flexing.

Apply a second, finer coat of jointing compound, feathering the edges. Sand lightly with fine-grit sandpaper after drying. Ensure primer is used before painting for a uniform finish.

Check that the framing is adequately spaced and securely fixed. Ensure the correct type and length of drywall screws are being used, and that they are driven in appropriately without over-penetrating the board's paper face.
